xampp - I'm trying to make a dynamic CSS (using php header) but I have problems in client -

i renamed stylesheet full.css.php , on beginning of file wrote code:

<?php     header("content-type: text/css; charset: utf-8");     //here want set css variables    $font_color = '#ccf';  ?> //here starts css body{     color: <?php echo $font_color?>; } 

the browser giving me this: resource interpreted script transferred mime type text/css: "http://localhost/root/_viewer/css/full.css.php"..

and error: "uncaught syntaxerror: unexpected token {" (this first brace body css declaration).
if in source, find file sent application/javascript file, not text/css:

<script type='application/javascript' src='_viewer/css/full.css.php'></script> 

i know dynamic css won't cached, it's fine me. it's more important have settings easy access. need fix this.

btw: i'm running under xampp !

-i forgot mention: i'm doing similar 1 of js files , it's working fine ( header("content-type: application/javascript"); )
